Unless I know I’m making a ton of variations of a model I’ll usually start from scratch every time. Maybe I’m blinded by my own experience but describing unique geometry with just words seems so much harder than just using regular cad. I design fixtures on a manufacturing line for a living and so I spend most of my time turning people’s ideas into 3d models and nobody can explain what they need with just words. People definitely try to explain what’s in their head but words aren’t enough for anything more complex than the examples on the page above. I always need to see a physical demonstration in person or a napkin sketch.
